What is the primary advantage of using hand instruments in the Atraumatic Restorative Treatment (ART) approach?
Faster caries removal
Lower risk of pulp exposure
Conservation of tooth structure
Increased wear resistance of restorations
Which material is most commonly used for restorations in ART due to its chemical bonding with both enamel and dentine?
Composite resin
Glass ionomer cement
Amalgam
Resin-modified glass ionomer
ART is indicated in all of the following situations except:
Inaccessible cavities for hand instruments
Small cavities involving dentin
Patients with special health care needs
Public health programs in remote areas
The release of which ion from glass ionomer cement in ART restorations helps prevent further caries progression?
Calcium
Fluoride
Phosphate
Magnesium
ART is contraindicated in which of the following conditions?
Small cavities involving only enamel
Patients who are cooperative
Low-income community settings
Presence of a swelling or abscess
Which of the following is a limitation of ART?
High cost of materials
Requirement of complex dental equipment
Hand fatigue during prolonged procedures
Inability to provide pain relief
Which instrument is used to remove soft carious dentin in ART?
Explorer
Dental hatchet
Spoon excavator
Applier/carver
Which of the following is a key principle of ART?
Use of local anesthesia in all cases
Complete removal of caries using handpieces
Cavity restoration with adhesive restorative materials
Treating all cavities, regardless of accessibility
In which of the following scenarios is ART preferred over conventional restorative methods?
When local anesthesia is mandatory
In multi-surface restorations for all patients
When high strength and wear resistance is essential
In populations with limited access to electricity
What is the primary method used to control moisture during ART procedures?
Cotton wool rolls
High-speed suction
Rubber dam isolation
Air drying
Which of the following best describes the role of fluoride in ART restorations?
Increases the bond strength of the material

Which of the following is a common reason for ART restoration failure?
Excessive use of local anesthesia
Contamination with saliva during the procedure
Use of resin-modified glass ionomer
Over-reduction of tooth structure
Which type of ART restorations is associated with the highest survival rates in primary teeth?
Multiple-surface restorations
Anterior teeth restorations
Restorations with amalgam
Single-surface restorations
